That is my problem area too. It is where females often store our fat. Leg raises are great. Try lying on your side and placing the top leg, knee bent in front of your bottom leg. Hold your ankle (if you want) and raise the lower leg. You can add ankle weights but I would encourage more reps rather than weights. Also doing squats with you toes pointed out and pushing up with your heels (this one hurts my hip so I don't do it but my friend does it).
Overall weight loss is the best way to get rid of a problem area. It may be the last area to go. Good luck with your workouts.
